A Code Judge That Declines to Guess Exposes How Little Model Verdicts Are Grounded
The paper offers two label-free measurements of whether a multi-agent verifier had evidence for its verdict, addressing judges that return confident reasoning indistinguishable from justified reasoning.
Model-as-judge evaluation now sits inside most agentic coding pipelines, both as a reward signal during training and as a gate before merge. A new preprint states the failure precisely: when one language model judges whether another's code…

Evaluation Design Becomes the Bottleneck
As capability claims outpace the validity of existing tests, benchmark construction turns into a contested research area and a gating input to enterprise procurement, so expect recurring purpose-built evaluations whose design, not whose leaderboard, is the news.
